iPhone 15 vs iPhone 16: Which One Should You Buy?

Each year, Apple refines its flagship smartphones with new features, more powerful hardware, and slight design tweaks. In 2024, the iPhone 16 series was introduced, bringing subtle but meaningful changes compared to the iPhone 15. For anyone trying to decide whether the jump from iPhone 15 to iPhone 16 is worth it, the differences matter. Let’s break down the details and see where these two devices stand apart.

Design and Build

At first glance, the iPhone 15 and iPhone 16 look almost identical. Both carry the same dimensions, sleek aluminum frames, and weigh nearly the same, with just a gram of difference. Apple hasn’t reinvented the wheel in terms of shape or overall design language, keeping the rounded corners and glossy back panel.

The most noticeable difference lies in the camera arrangement. On the iPhone 15, the dual-lens setup follows Apple’s traditional diagonal design. With the iPhone 16, Apple switched to a vertical alignment, a nod to the upcoming spatial video features and also a subtle design refresh.

Another significant update is the inclusion of new hardware buttons. The iPhone 16 introduces the Action Button, previously reserved for the Pro models. This button can be customized to perform tasks such as launching apps, starting voice memos, or triggering shortcuts. Alongside it, there’s a brand-new Camera Control button, giving users quick access to camera functions without relying on the display. This physical control will appeal to photography enthusiasts who want quicker interaction.

Apple also reinforced durability this year by upgrading the iPhone 16 with a stronger ceramic shield front glass, making it more resistant to scratches and accidental drops.

Quick Comparison

Disclaimer: Specs are based on official sources and leaks; final details may vary.

Display Quality

When comparing the screens, Apple has kept the core specifications unchanged. Both models sport a 6.1-inch OLED display with a crisp resolution, excellent HDR support, and vibrant color reproduction. Brightness levels are impressive on both devices, reaching up to 2000 nits peak brightness outdoors, ensuring visibility under direct sunlight.

One drawback, however, is the continued use of a 60Hz refresh rate. While competitors have widely embraced higher refresh rates, Apple continues to reserve smoother scrolling and animations for its Pro lineup. Still, everyday users will find the display sharp, color-accurate, and responsive.

Overall, while the panel itself hasn’t evolved much between the iPhone 15 and iPhone 16, the tougher ceramic shield and minor software optimizations give the new model an edge in durability and user experience.

Audio and Speakers

Both smartphones feature stereo speakers, delivering rich, clear audio suitable for music, video playback, and gaming. The iPhone 16 offers slightly louder output compared to the iPhone 15, but the difference is subtle. For most users, both models deliver excellent sound with good balance between highs, mids, and bass.

Apple has also upgraded the microphones on the iPhone 16, equipping them with studio-grade quality for improved call clarity, voice recording, and video capture. This makes a difference for vloggers, content creators, and anyone who frequently records audio on the go.

Performance and Benchmarks

Performance is one of the biggest areas of distinction in the iPhone 15 vs iPhone 16 debate. The iPhone 15 runs on the A16 Bionic chip, a fast and reliable processor that powered the Pro models from 2022. It’s still highly capable for multitasking, gaming, and demanding apps.

The iPhone 16, however, is powered by Apple’s brand-new A18 chip, which brings a significant performance boost. Along with faster CPU and GPU speeds, the chip is more power-efficient and includes a stronger neural processing unit (NPU) for handling AI-driven tasks. This matters because Apple is rolling out its new Apple Intelligence features, which will rely heavily on onboard processing power. While the iPhone 15 will support some of these features, the iPhone 16 is expected to run them more smoothly.

When it comes to benchmarks, the numbers speak for themselves:

• iPhone 15 (A16 Bionic):
  
  • Geekbench 6 : ~6526
    
  • AnTuTu score: ~1354651
    
• iPhone 16 (A18):
  
  • Geekbench: ~7927
    
  • AnTuTu score: ~1727276
    

This leap in scores highlights how much faster and future-ready the iPhone 16 truly is. For gamers, heavy multitaskers, or those planning to keep their phone for years, the newer chip is a compelling reason to upgrade.

Battery and Charging

Battery life has also seen improvements with the iPhone 16. Thanks to the efficiency of the A18 chip and optimized power management, it lasts longer than the iPhone 15 in endurance tests. In mixed usage scenarios, the iPhone 15 comfortably lasts a full day, while the iPhone 16 stretches closer to a day and a half.

Charging speeds remain unchanged, with both phones charging up to 60% in about 30 minutes using a 20W adapter. However, the iPhone 16 does bring an upgrade in wireless charging, now supporting faster speeds with MagSafe accessories.

The practical difference is that while both devices deliver reliable daily performance, the iPhone 16 provides a bit more freedom for heavy users who don’t want to worry about running out of charge late in the evening.

Camera Upgrades

Apple continues to refine its photography system, though the changes here are more subtle. Both models feature a 48MP main wide camera paired with a 12MP ultra-wide camera. On paper, it may sound identical, but the iPhone 16 brings meaningful tweaks.

The ultra-wide lens on the iPhone 16 has a brighter aperture and autofocus support, enabling it to double as a macro camera. This lets users capture detailed close-up shots, something the iPhone 15 cannot replicate. In daylight, both cameras produce sharp, color-accurate photos with Apple’s signature natural tone and wide dynamic range.

At night, the brighter ultra-wide on the iPhone 16 produces clearer, more detailed images with reduced noise. The main cameras, however, remain almost indistinguishable between the two models, both delivering excellent performance.

For video recording, both smartphones remain industry leaders with 4K at 60fps support, cinematic mode, and outstanding stabilization. The iPhone 16 enhances audio recording with spatial video and audio capture, a feature designed for Apple’s Vision Pro ecosystem. This means the iPhone 16 is better prepared for immersive video experiences in the future.

Real-World Experience

On a day-to-day basis, the differences between the iPhone 15 and iPhone 16 aren’t groundbreaking, but they do add up. The new hardware buttons on the iPhone 16 make quick actions easier. Its improved chip ensures smoother performance in high-demand situations. The battery lasts longer, and the upgraded ultra-wide camera provides extra flexibility.

For many users, the iPhone 15 will still feel like a modern, powerful phone. It handles apps, gaming, photography, and video recording with ease. However, those wanting future-proof performance, better AI integration, and small but useful upgrades will find the iPhone 16 a more compelling option.

Conclusion: Which One Should You Buy?

Choosing between the iPhone 15 and iPhone 16 comes down to priorities. If budget is a concern, the iPhone 15 is still an excellent device that delivers nearly everything the newer model does at a lower price. For users who don’t push their phones to the limit, it remains a smart and reliable choice.

On the other hand, if you value longer battery life, a more powerful chipset, improved AI support, new hardware controls, and a better ultra-wide camera, then the iPhone 16 is the clear winner. It may not revolutionize the lineup, but it’s a refined and forward-looking device that makes it easier to justify the upgrade.
